“ Had I the heavens' embroidered cloths,
Enwrought with golden and silver light,
The blue and the dim and the dark cloths
Of night and light and the half light,”

NGC 188... One of the most ancient open clusters, NGC 188 in the constellation Cepheus,is masked by galactic cirrus less than 5 degrees from Polaris. It was discovered by John Herschel in 1825. Unlike most open clusters that drift apart after a few million years because of the gravitational interaction of our galaxy, NGC 188 lies far above the plane of the galaxy and is one of the most ancient of open clusters known, at approximately 5 billion years old.

The Coma Cluster (Abell 1656) is a large cluster of galaxies that contains over 1,000 identified galaxies. Along with the Leo Cluster (Abell 1367), it is one of the two major clusters comprising the Coma Supercluster.] It is located in and takes its name from the constellation Coma Berenices.<br />
<br />
The cluster's mean distance from Earth is 99 Mpc (321 million light years). Its ten brightest spiral galaxies have apparent magnitudes of 12–14 . The central region is dominated by two giant elliptical galaxies: NGC 4874 and NGC 4889. The cluster is within a few degrees of the north galactic pole on the sky. Most of the galaxies that inhabit the central portion of the Coma Cluster are ellipticals. Both dwarf, as well as giant ellipticals, are found in abundance in the Coma Cluster.<br />
<br />
As is usual for clusters of this richness, the galaxies are overwhelmingly elliptical and S0 galaxies, with only a few spirals of younger age, and many of them probably near the outskirts of the cluster.<br />
<br />
The full extent of the cluster was not understood until it was more thoroughly studied in the 1950s by astronomers at Mount Palomar Observatory, although many of the individual galaxies in the cluster had been identified previously.<br />
<br />
An extended X-ray source centered at 1300+28 in the direction of the Coma cluster of galaxies was reported before August 1966. This X-ray observation was performed by balloon, but the source was not detected in the sounding rocket flight launched by the X-ray astronomy group at the Naval Research Laboratory on November 25, 1964. A strong X-ray source was observed by the X-ray observatory satellite Uhuru close to the center of the Coma cluster and this source was suggested be designated Coma X-1.<br />
<br />
The Coma cluster contains about 800 galaxies within a 100 x 100 arc-min area of the celestial sphere.<br />

Abell 85, aka CTB 1, or LBN576, is a large supernova remnant (SNR) located in Cassiopeia. Originally catalogued by George Abell as a planetary nebula, it soon became evident that it was actually a SNR. It was also recognized as a radio source and acquired the alternative designation CTB 1. Abell 85 has relatively weak [OIII] and H-Beta emission compared to the "traditional" supernova-remnant lines of H-alpha, [NII], and [SII]. For visual observers, the gain in contrast using [O III] and H-Beta filters appears to be minimal. In fact, this object is often considered as one of the most challenging for visual observation [Ultimate challenges] and remains a good test for CCD photography.](https://photos.smugmug.com/Astronomy/Night-Over-Ontario/i-KXm5zmg/4/b91b4bd7/Ti/ABELL%2085%207%20BEST%20with%20LR-Ti.jpg)
